Unit 1: Bio-Chemistry

Question 1

Polarity

Answer 1

Refers to unequal charge distribution in a molecule such as water, which has a positive region although it is neutral overall.

Question 2

Acid

Answer 2

is defined as any substance that increases the concentration of H+ in a solution, or any Proton Donor

Question 3

Base

Answer 3

is defined as any substance that removes H+ from a solution, or any
proton acceptor

Question 4

Volume

Answer 4

in L or mL

Question 5

Concentration

Answer 5

in mol/L

Question 6

Mass

Answer 6

in grams

Question 7

Molar Mass

Answer 7

in g/mol

Question 8

Moles

Answer 8

mol

Question 9

Molecular Formula

Answer 9

Carbon and then Hydrogen and all other molecules in alphabetical in which they appear in the periodic table.

Question 10

Skeletal Formula

Answer 10

Taking out the Carbon and Hydrogen’s because every organic material has the two molecules to make it look neater.

Question 11

Biomolecules

Answer 11

C,H,N,O,P,S

Question 12

Monomers

Answer 12

simple unit molecules form which larger molecules are build

Question 13

Condensation Synthesis

Answer 13

The H is removed from one monomer and combined with OH from the other monomer to form a molecule of water.

Question 14

Polymers

Answer 14

Chains exceeding 3 units

Question 15

Oligomers

Answer 15

Chains of 3 to 20 monomers

Question 16

Hydrolysis

Answer 16

When a molecule of water is split and the H and OH are used to replace the bond between monomers.

Question 17

Triaglycerides

Answer 17

Fats and Oils

Question 18

Carbohydates

Answer 18

Group of molecules that are loosely defined as containing the elements carbon, hydrogen, and oxygen.

Question 19

Monosaccharides

Answer 19

Small water soluble and rich in chemical energy which make them well suited as vehicles for storing moving potential energy.

Question 20

Disaccharides

Answer 20

Consist of two monosaccharides bonded together. They store twice as much energy per molecule and produce less osmotic potential in a cell.

Question 21

Polysaccharides

Answer 21

Insoluble molecule which cannot diffuse or interfere with reactions. They string glucose into long helical chains.

Question 22

Lipids

Answer 22

Non-polar molecules and are fat soluble. Strong insulators against both heat and electricity. Very rich in C-H bonds.

Question 23

Hydrophobic

Answer 23

Waterproofing (from lipids and structure of cell membranes)

Question 24

Triglycerides

Answer 24

Fat and oils.

Question 25

Waxes

Answer 25

Consist of a complex of organic ester bonds formed by a long chain of alcohol and bonded to a fatty acid.

Question 26

Steroids

Answer 26

A family of multiple-ring molecules used both as hormones as a membrane stabilizer.
